FIELD OF DISCLOSURE

The disclosure relates to the field of plant breeding and, morespecifically, to watermelon variety NUN 11602 WMW. The disclosurefurther relates to vegetative reproductions of watermelon variety NUN11602 WMW, methods for tissue culture of watermelon variety NUN 11602WMW and regenerating a plant from such a tissue culture and tophenotypic variants of watermelon variety NUN 11602 WMW.

BACKGROUND

The goal of plant breeding is to combine various desirable traits in asingle variety. Such desirable traits may include greater yield,resistance to diseases, insects or other pests, tolerance to heat anddrought, better agronomic quality, higher nutritional value, enhancedgrowth rate and improved fruit properties.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same genotype. A plant cross-pollinates if pollen comes to it from aflower of a different genotype. Plants that have been self-pollinatedand selected for (uniform) type over many generations become homozygousat almost all gene loci and produce a uniform population of truebreeding progeny of homozygous plants. A cross between two suchhomozygous plants of different lines produces a uniform population ofhybrid plants that are heterozygous for many gene loci. The extent ofheterozygosity in the hybrid is a function of the genetic distancebetween the parents. Conversely, a cross of two plants each heterozygousat a number of loci produces a segregating population of hybrid plantsthat differ genetically and are not uniform. The resultingnon-uniformity makes performance unpredictable.

The development of uniform varieties requires the development ofhomozygous inbred plants, the crossing of these inbred plants to makehybrids, and the evaluation of the hybrids resulting from the crosses.Pedigree breeding and recurrent selection are examples of breedingmethods that have been used to develop inbred plants from breedingpopulations. Those breeding methods combine the genetic backgrounds fromtwo or more plants or various other broad-based sources into breedingpools from which new lines are developed by selfing and selection ofdesired phenotypes. The new plants are evaluated to determine which havecommercial potential.

One valuable crop that has been subject to breeding programs iswatermelon, a member of the Cucurbitacea family. The genus Citrullusoriginated in Africa. The plant is a large and sprawling annual, grownfor its fruit. The fruit of watermelon is often colored attractively,commonly red. Watermelon can contain black seeds, which are consideredundesirable for certain uses. Watermelon is primarily consumed fresh.The fruit can be eaten fresh as dessert, snack, salad, or juice.Watermelon is also processed to produce roasted seeds, pickled rind,pickled fruit, or powdered juice.

Watermelon (Citrullus lanatus) can occur as a diploid, triploid ortetraploid. Seedless watermelon fruits are produced by using pollen fromdiploid male parent plants to fertilize flowers of tetraploid maternalparent plants. Pollination of the tetraploid flowers with diploid pollenleads to hybrid F1 seeds which are triploid (see, e.g., Kihara, 1951,Proceedings of American Society for Horticultural Science 58: 217-230;Eigsti 1971, Hort Science 6: 1-2). The triploid hybrid plants grown fromthese F1 seeds are self-infertile as they produce sterile pollen due tochromosome imbalance and need to be pollinated by a diploid pollenizerto produce watermelon fruit. Triploid plants are, therefore,interplanted with pollenizer plants for fruit production. The “seedless”fruit produced after pollination on the triploid hybrid plant are nottruly seedless, but often contain some undeveloped, small, pale seeds,which are edible. Plants are generally planted at a ratio of 1pollenizer per every 2-4 triploid plants. Triploid plants andpollenizers are either planted in separate rows (e.g., 1 row ofpollenizer and 2-4 rows of triploids), or interplanted within rows(e.g., planting 1 pollenizer plant in between 2 to 3 triploid plants inthe same row), or interplanted in narrow rows between rows of triploids(see, e.g., Table 2 of US2006/0168701 and U.S. Pat. No. 8,418,637, whichis herein incorporated by reference in its entirety). The fruit producedon the pollenizer plants preferably has a different rind pattern fromthe fruit on the triploid hybrids, so that these can be easilydistinguished.

Grading of fruits is usually done by fruit weight, to distinguish “mini”watermelons, with weights of less than 6 pounds (2.72 kg), “icebox”watermelons with weights of 8-12 pounds (3.62 kg-5.44 kg) or, accordingto others, of 6 to 15 pounds (2.72 kg to 6.8 kg) and “picnic”watermelons of above the icebox size, so either above 12 pounds (above5.44 kg) or above 15 pounds (above 6.8 kg). Furthermore, watermelonfruit flesh can have various colors, including various tints of red,pink, orange, and yellow.

Watermelons are produced across the United States with the most volumeof production coming from Texas, Florida, Georgia, and California. Theconsumer demand for watermelon, in particular for seedless (triploid)varieties is continuously growing due to its health benefits. Thistranslates to an increased demand for improved watermelon varieties ofdifferent sizes, shapes, and fruit quality. Other objectives includevarying the color, texture, and flavor of the fruit, absence of seeds,disease or pest resistance, optimizing flesh thickness, yield,suitability to various climatic circumstances, solid content (% drymatter), and sugar content.

Such an embryocomprises two sets of chromosomes derived from watermelon variety NUN11602 WMW, if it is produced from self-pollination of watermelon varietyNUN 11602 WMW, while an embryo derived from cross-fertilization ofwatermelon variety NUN 11602 WMW will comprise only one set ofchromosomes from said variety.

A plant having “all the physiological and morphological characteristics”of a referred-to-plant means a plant showing the physiological andmorphological characteristics of the referred-to-plant when grown underthe same environmental conditions, preferably in the same experiment;the referred-to-plant can be a plant from which it was derived, e.g.,the progenitor plant, the parent, the recurrent parent, the plant usedfor tissue- or cell culture, etc. A physiological or morphologicalcharacteristic can be a numerical characteristic or a non-numericalcharacteristic. In one aspect, a plant has “all but one, two, or threeof the physiological and morphological characteristics” of areferred-to-plant, or “all the physiological and morphologicalcharacteristics” of Tables 1 and 2 or “all or all but one, two or threeof the physiological and morphological characteristics” of Tables 1 and2.

The physiological and/or morphological characteristics mentioned aboveare commonly evaluated at significance levels of 1%, 5% or 10% if theyare numerical (quantitative), or for having an identical degree (ortype) if not numerical (not quantitative), if measured under the sameenvironmental conditions. For example, a progeny plant or a Single LocusConverted plant or a mutated plant of variety NUN 11602 WMW may have oneor more (or all) of the essential physiological and/or morphologicalcharacteristics of said variety listed in Tables 1 and 2, as determinedat the 5% significance level (i.e., p<0.05), when grown under the sameenvironmental conditions.

“Distinguishing characteristics” or “distinguishing morphological and/orphysiological characteristics” refers herein to the characteristicswhich distinguish the new variety from other watermelon varieties, suchas the Reference Variety (e.g., are different), when grown under thesame environmental conditions. The distinguishing characteristicsbetween watermelon variety NUN 11602 WMW and Reference Variety aredescribed herein and also can be seen in Table 3. When comparingwatermelon variety NUN 11602 WMW to other varieties, the distinguishingcharacteristics may be different. In one aspect, the distinguishingcharacteristics may include one, two, three, or more (or all) of thecharacteristics listed in Tables 1 and 2. All numerical distinguishingcharacteristics are statistically significantly different at p<0.05between NUN 11602 WMW and the other variety, e.g. the Reference Variety.

Watermelon variety NUN 11602 WMW has the following distinguishingcharacteristics when compared to the Reference Variety as shown in Table3: 1) fewer main stems at crown; 2) shorter mature leaf length; 3)smaller leaf blade size; 4) thinner mature leaf width; 5) strongerdegree of leaf blade lobing; 6) moderate yellowish green color of matureleaf; 7) shorter petiole length; 8) smaller petiole width; 9) broadelliptic mature fruit shape in longitudinal section; 10) more roundedand less acute apical part; 11) shorter mature fruit length; 12) smallermature fruit diameter; 13) lighter mature fruit average weight; 14)darker olive green (primary) color of mature fruit; 15) very weaklyconspicuous veins; 16) no stripes, only veins; 17) more waxy layer; 18)very weakly conspicuous stripes; 19) tender rind texture; 20) thinnerrind at blossom end; 21) thinner rind at sides; and 22) thinner rind atstem end, when grown under the same environmental conditions.

Thus, a watermelon plant “comprising the distinguishing characteristicsof variety NUN 11602 WMW” (such as a progeny plant) refers herein to aplant which does not differ significantly from said variety in thedistinguishing characteristics above. Therefore, in one aspect a plantis provided which does not differ significantly from watermelon varietyNUN 11602 WMW in the distinguishing characteristics above.

Similarity and differences between two different plant lines orvarieties can be determined by comparing the number of morphologicaland/or physiological characteristics that are the same (i.e.,statistically not significantly different) or that are different (i.e.,statistically significantly different) between the two plant lines orvarieties using plants grown under the same environmental conditions. Anumerical characteristic is considered to be “the same” when the valuefor a numeric characteristic is not significantly different at the 1%(p<0.01) or 5% (p<0.05) significance level, using T-test, a standardmethod known to the skilled person. Non-numerical or “degree” or “type”characteristic is considered “the same” when the values have the same“degree” or “type” when scored using USDA and/or UPOV descriptors, ifthe plants are grown under the same environmental conditions.

A “plant line” is, for example, a breeding line which can be used todevelop one or more varieties. A breeding line is typically highlyhomozygous.

“Hybrid variety” or “F1 hybrid” refers to the seeds harvested fromcrossing two inbred (nearly homozygous) parental lines. For example, thefemale parent is pollinated with pollen of the male parent to producehybrid (F1) seeds on the female parent.

“Regeneration” refers to the development of a plant from cell culture ortissue culture or vegetative propagation.

“Vegetative propagation”, “vegetative reproduction” or “clonalpropagation” are used interchangeably herein and mean a method of takinga plant part and inducing or allowing that plant part to form at leastroots, and also refer to the plant or plantlet obtained by that method.Optionally, the vegetative propagation is grown into a mature plant. Theskilled person is aware of what plant parts are suitable for use in themethod.

“Crossing” refers to the mating of two parent plants. The termencompasses “cross-pollination” and “selfing”.

“Selfing” refers to self-pollination of a plant, i.e., the transfer ofpollen from the anther to the stigma of the same plant.

“Cross-pollination” refers to the fertilization by the union of twogametes from different plants.

A “pollenizer” is a watermelon plant that can be used to pollenizetriploids. Preferably, such a plant produces a very large amount ofpollen.

As used herein, the terms “resistance” and “tolerance” are usedinterchangeably to describe plants that show no symptoms orsignificantly reduced symptoms to a specified biotic pest, pathogen,abiotic influence or environmental condition compared to a susceptibleplant. These terms are optionally also used to describe plants showingsome symptoms but that are still able to produce marketable product withan acceptable yield.

The term “traditional breeding techniques” encompasses herein crossing,selfing, selection, doubled haploid production, embryo rescue,protoplast fusion, marker assisted selection, mutation breeding etc. asknown to the breeder (i.e., methods other than geneticmodification/transformation/transgenic methods), by which, for example,a genetically heritable trait can be transferred from one watermelonline or variety to another.

“Backcrossing” is a traditional breeding technique used to introduce atrait into a plant line or variety. The plant containing the trait iscalled the donor plant and the plant into which the trait is transferredis called the recurrent parent. An initial cross is made between thedonor parent and the recurrent parent to produce a progeny plant.Progeny plants which have the trait are then crossed to the recurrentparent. After several generations of backcrossing and/or selfing therecurrent parent comprises the trait of the donor. The plant generatedin this way may be referred to as a “single trait converted plant”. Thetechnique can also be used on a parental line of a hybrid.

“Progeny” as used herein refers to a plant obtained from a plantdesignated NUN 11602 WMW. A progeny may be obtained by regeneration ofcell culture or tissue culture or parts of a plant of said variety orselfing of a plant of said variety or by producing seeds of a plant ofsaid variety. In further aspects, progeny may also encompass plantsobtained from crossing of at least one plant of said variety withanother watermelon plant of the same variety or another variety or line,or with wild watermelon plants. A progeny may comprise a mutation or atransgene. A “first generation progeny” is the progeny directly derivedfrom, obtained from, or derivable from the parent plant by, e.g.,traditional breeding methods (selfing and/or cross-pollinating) orregeneration (optionally combined with transformation or mutation).Thus, a plant of variety NUN 11602 WMW is the male parent, the femaleparent or both of a first generation progeny of watermelon variety NUN11602 WMW. Progeny may have all the physiological and morphologicalcharacteristics of variety NUN 11602 WMW, when grown under the sameenvironmental conditions. Using methods such as backcrossing, recurrentselection, mutation or transformation, one or more specificcharacteristics may be introduced into said variety, to provide or aplant comprising all but 1, 2, or 3 of the morphological andphysiological characteristics of variety NUN 11602 WMW.

The terms “gene converted” or “conversion plant” or “single locusconverted plant” in this context refer to watermelon plants which aredeveloped by traditional breeding techniques, e.g., backcrossing or viagenetic engineering or through mutation breeding, wherein essentiallyall of the desired morphological and physiological characteristics ofthe parent variety or line are recovered, in addition to the one or morecharacteristics introduced into the parent via e.g., the backcrossingtechnique (optionally including reverse breeding or reverse synthesis ofbreeding lines). It is understood that not only the addition of afurther characteristic (e.g., addition of gene conferring a furthercharacteristic, such as a disease resistance gene), but also thereplacement/modification of an existing characteristic by a differentcharacteristic is encompassed herein (e.g., mutant allele of a gene canmodify the phenotype of a characteristic).

Likewise, a “Single Locus Converted (Conversion) Plant” refers to plantsdeveloped by plant breeding techniques comprising or consisting ofmutation and/or by genetic transformation and/or by traditional breedingtechniques, such as backcrossing, wherein essentially all of the desiredmorphological and physiological characteristics of a watermelon varietyare recovered in addition to the characteristics of the single locushaving been transferred into the variety via the abovementionedtechnique, or wherein the morphological and physiologicalcharacteristics of the variety has been replaced/modified in thevariety. In case of a hybrid, the gene may be introduced in the male orfemale parental line.

“Average” refers herein to the arithmetic mean.

The term “mean” refers to the arithmetic mean of several measurements.The skilled person understands that the appearance of a plant depends tosome extent on the growing conditions of said plant. Thus, the skilledperson will know suitable growing conditions for watermelon variety NUN11602 WMW. The mean, if not indicated otherwise within this application,refers to the arithmetic mean of measurements on at least 10 different,randomly selected plants of a variety or line.

For the purpose of this disclosure, the “sequence identity” ofnucleotide sequences, expressed as a percentage, refers to the number ofpositions in the two optimally aligned sequences which have identicalresidues (×100) divided by the number of positions compared. A gap,i.e., a position in the pairwise alignment where a residue is present inone sequence but not in the other, is regarded as a position withnon-identical residues. A pairwise global sequence alignment of twonucleotide sequences is found by aligning the two sequences over theentire length according to the Needleman and Wunsch global alignmentalgorithm described in Needleman and Wunsch, 1970, J. Mol. Biol.48(3):443-53). A full implementation of the Needleman-Wunsch globalalignment algorithm is found in the needle program in The EuropeanMolecular Biology Open Software Suite (see, e.g., EMBOSS, Rice et al.,Trends in Genetics June 2000, vol. 16, No. 6. pp. 276-277).

The disclosure also provides methods for determining the identity ofparental lines of plants described herein, in particular the identity ofthe female line.

Using methods known in the art such as “reverse synthesis of breedinglines” or “reverse breeding”, it is possible to produce parental linesfor a hybrid plant such as watermelon variety NUN 11602 WMW. A skilledperson can take any individual heterozygous plant (called a“phenotypically superior plant” in Example 2 of US2015/0245570 herebyincorporated by reference in its entirety; watermelon variety NUN 11602WMW is such a plant) and generate a combination of parental lines(reverse breeding parental lines) that, when crossed, produce thevariety NUN 11602 WMW. It is not necessary that the reverse breedingparental lines are identical to the original parental lines. Such newbreeding methods are based on the segregation of individual alleles inthe spores produced by a desired plant and/or in the progeny derivedfrom the self-pollination of that desired plant, and on the subsequentidentification of suitable progeny plants in one generation, or in alimited number of inbred cycles.
